After Solyndra’s bankruptcylast year focused an unflattering spotlight on the solar business, SolarCity and other companies gave up hope for federal loan guarantees. But SolarCity has found other funding for its projects through the likes ofGoogle Inc. and PG&E Corp.

The company, launched in 2006, also pioneered a leasing model that helped put previously unaffordable solar panels within reach for the average homeowner. Research group IBISWorld recently named solar panel production among the fastest-growing industries in the country along with yoga studios and hot sauce.

SolarCity, one of the country’s largest residential and commercial solar installers, skimped on the details when announcing its IPO plans Monday — the company did not disclose share pricing or amount or a projected debut date. The Securities and Exchange Commission is reviewing SolarCity’s draft registration statement.
